Congestion notification device and congestion control method in asynchronous transmission mode network

摘要

end. The technical field to which the invention described in the claims belongs;Congestion notification device and congestion control method in ATM network;I. The technical problem that the invention is trying to solve;We will implement a simple circuit and fast and efficient congestion notification to reduce the delay of congestion notification and control congestion by connection and to notify when congestion occurs due to buffer overflow.;All. Summary of the Solution of the Invention;The present invention provides a buffer overflow notification in an internal buffer by providing a congestion notification device in all positions where congestion such as buffer overflow or the like may occur, for example, the interface units 34 to 44, the switch fabric unit 32, and the control / maintenance unit 46. Occurs, the congestion indicating bit, that is, the EFCI bit is set directly in the input ATM cell.;la. Important uses of the invention;Congestion Control in ATM Networks
